We have been looking online (without success) for a list of mathematical functions for use in WeBWorK by problem authors. That is, we aren't looking for sine, cosine, log, etc. as used by the students to input answers. We're looking for functions like "round" that can be used when creating problems.
(We know there's a rounding function because we guessed that there should be and tried it, but presumably there's a better way than guessing!)
Can anyone point me in the direction of such a list?
You can decipher many of the functions available by looking at
Anything of the form
sub xxxxx {
$a = shift
$b = shift
}
creates a function xxxxx(a, b) which you can use.
or
sub xxxxx {
... $_[0], $_[1], $_[2]
.....
}
would be a function xxxxx(a,b,c) with three arguments.
The POD documentation in this file is not correctly written. If it were
you would be able to use the PGauxiliaryFunctions.pl link and description
on the page
http://webwork.maa.org/pod/pg_TRUNK/ to answer you question.
Perhaps someone learning to write PG and perl would be willing to fix the POD documentation and submit a pull request to github.com/openwebwork so that it is easier to find the answer to your question. It would be a good learning project.

Perfect, thank you.
I'll pass this along, and see if we have time to look at that documentation.
